Numerical Study on the Effects of Design Parameters on the Spray Characteristics of Fire Suppression Nozzles
소화노즐의 분무특성에 대한 설계 변수 영향의 수치해석적 연구
Abstract
Numerical investigation has been performed to simulate the spray characteristics in mist-spray fire suppression nozzles in sense of design parameters. Two key shape factors in nozzle orifices. i.e. diameter and length are chosen as simulation parameters. Commercial softwares, FLUENT and FDS with the proper modelings were applied as numerical tools. Main performances of nozzles, i.e., K-factors, spray angles, droplet size, jet velocities and fire suppression time are analyzed for each parameter to find optimal design conditions.
